MDDP is an abbreviation for Micro Device Display. MDDP is a rear projection television technology that uses an extremely thin semiconductor device called a microdisplay to create the image.
The Micro Display Devices play the most critical role in delivering the revolutionary visual entertainment provided by MDDP. Cutting-edge semiconductor processing technology makes it possible to shrink the components and provide the highest possible image quality into an area that is less than two centimeters across. MDDP TVs are currently implemented with three different types of Micro Display Devices.
From left to right: The DLP has many tiny mirrors embedded into a piece of silicon; the High temperature polysilicon (HTPS) Micro Device uses liquid crystal silicon with transmissive technology; and the Liquid Crystal on Silicon (LCOS) Micro Device uses liquid crystal silicon with a reflective layer.
There are three representative types of Micro Display Devices: DLP® chips, HTPS, and LCOS.
The DLP® chip is an image display device manufactured by Texas Instruments. DLP is an abbreviation for Digital Light Processing. This unique technology forms an image by directing light toward the tiny mirrors, each of which corresponds to a pixel, on the DLP chip surface.
HTPS is an abbreviation for High Temperature Poly Silicon, and is a type of active matrix transmissive LCD. This LCD is compact, has extremely high resolution and high contrast, and has the capacity to include built-in drivers.
LCOS (Liquid Crystal On Silicon) is a reflective liquid crystal device. It is gaining attention as an emerging Micro Display Device for projectors, providing both high brightness and high resolution.
